Roller skate with a micro adjustment device

ABSTRACT

A roller skate with a micro adjustment device includes a wheel frame, a quarter and a vamp, the wheel frame has a first chain and slots on both sides, and a second chain on top surface thereof, the vamp also comprises a third chain and holes on both sides as well, a quick release device is inserted with its shaft through the holes of the vamp and the slots of the wheel frame that aligns the first chain and the third chain, the shaft secures a gear aligns with the second chain, by tightening and loosening of the quick release device, the gear is adjustable with regard to the second chain, thus the third chain of the vamp is adjustable along the first chain of the wheel frame.

FIELD OF THE INVENTION

[0001] This invention relates to a roller skate, and more particularly to a roller skate with a micro adjustable device for different users.

BACKGROUND OF THE INVENTION

[0002] There are various brands of roller skates on the market. Each skate has a size to fit a user with the size of feet. However, when the user grows up, the size will not fit anymore, and the skate has to be replaced, which is not cost effectiveness. An adjustable skater is disclosed later on, which comprises a front and a rear sections, by adjusting one of the sections, the skater's size may be changed to fit users with different sizes of feet. These skaters may have a heavy weight, which will hurt the user's ankles. Further the adjustment is large scale, therefore, in many times the adjusting size is either slightly large or small.

[0003] In view of these and many other shortcomings, the inventor has invented the present invention to do a micro adjustment.

SUMMARY OF THE INVENTION

[0004] It is the primary object of the present invention to provide a roller skate with a micro adjustment device, which uses a micro adjustment to acquire the most desirable size for a user.

[0005] It is another object of the present invention to provide a roller skate with a micro adjustment device, which uses less parts, therefore has less weight and less burden to a user.

[0006] It is a further object of the present invention to provide a roller skate. with a micro adjustment device, which is inexpensive in manufacture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] A roller skate with a micro adjustment device of the present invention is generally composed of a wheel frame 1, a quarter 2, and a vamp 3.

[0013] The wheel frame 1 is identical to the prior art, and which comprises a top board 17 with two side boards 18 extending downward for both sides, underneath the side boards 18, there are four wheels 16 secured thereat. The improvement is that a pair of first chains 12 is formed on each side board 18, and each first chain 12 has a slot 11, the top board 17 has a second chain 13 underneath the surface, and the top of the wheel frame 1 comprises a pair of front holes 14 and a rear hole 15.

[0014] The quarter 2 is secured to the rear section of the top board 17 of the wheel frame 1, having a pair of front holes 21 and a rear hole 22.

[0015] The vamp 3 is secured on the front section of the top board 17 of the wheel frame 1, with two sides extending downward to form side boards 31 which has a third chain 33 at inner end in align with the first chain 12. The third chain 33 comprises a hole 32 corresponding to the slot 11. The vamp 3 has a slot 38 at front bottom. The quarter 2 is secured to the vamp 3 by a quick release device 34. The quick release device 34 uses a pin 35 to connect a disc 361 of a shaft 36. The shaft 36 has a gear 37 to mesh with the second chain 13 of the wheel frame 1.

[0016] To assemble the present invention, as shown in FIGS. 2 and 3, insert a bolt A and a washer Al through the rear hole 22 of the quarter 2 and the rear hole 15 of the wheel frame 1 and secured by a nut A2 from the other side thereof. Uses two rivets B to insert through the front holes 21 of the quarter 2, the slot 38 of the vamp 3 and the front holes 14 of the wheel frame 1 and riveted with washers B 1 from the other end thereof. This way, the first chain 12 of the wheel frame 1 and the third chain 33 of the vamp 3 are meshed together, as shown in FIG. 4. The gear 37 is placed between the two side boards 18 of the wheel frame 1. The shaft 36 of the quick release device 34 is inserted through a washer C1, the hole 32 of the vamp 3, the slot ii of the wheel frame 1, and the gear 37, and then fastened by a C-snap ring C. This prevents the quick release device 34 loosening from the hole 32 of the vamp 3 and the sot 11 of the wheel frame 1. This step also makes the gear 37 of the shaft 36 meshes with the second chain 13, thus the wheel frame 1, the quarter 2 and the vamp 3 are secured together.

[0017] When in use, as shown in FIG. 4, loosen the quick release device 34, which releases the meshing status of the first chain 12 of the wheel frame 1 from the third chain 33 of the vamp 3, thus the wheel frame 1 and the vamp 3 are able to move with respect to each other. By rotating the shaft 36 of the quick release device 34, also rotate the gear 37 which links the second chain 2 to rotate simultaneously, and the shaft 36 slides along the slot 11 of the wheel frame 1, whereas the vamp 3 may also slide along the rivet B with the slot 38. When the vamp 3 has reached to an appropriate position, as shown in FIG. 5, the quick release device 34 is tightened to force the third chain 33 of the vamp 3 and the first chain 12 of the wheel frame 1 meshing together, and confine any relative movement of the two chains 12 and 33. Since the sizes of the teeth of the first chain 12, the third chain 33 and the gear 37 are relative small, the adjustments are also very small, which can fit the size to the most appropriation. 

I claim:
